If you're interested in staying with 80's friction-shift gear, then you can't beat Suntour for that era. I have an '83 Trek I've set up with Cyclone MkII front and MkII GT rear derailleur, some make of Sugino period 110/74BCD crankset 28/44/52 triple front, 6s rear freewheel on a 126 hub (I think I went 12-24, but it would handle more).


I love my Campy, but this setup will work better for an 80's triple setup; and you could buy the stuff you need for a lot less than you could sell the stuff you don't.
